Calf Rennet Steeped from Dried Stomach

Traditional rennet is steeped from the stomachs of young calves. The dried, cleaned stomach is sliced, soaked in salt water with a little vinegar for a night to several days, and strained. The liquid curdles milk for cheese. Test each batch, as the strength varies. The picture: our diagram, slices soaking, straining and the bottled rennet.
